 * # Build Terrain Mesh
 *
 * ## Description
 *
 * Builds a triangular mesh from elevation data. Useful for rendering elevation data as a 3D model.
 *
 * This is a port of the [martini](https://github.com/mapbox/martini) codebase to be compatible with this library.
 *
 * NOTE: Defaults to the Mapbox elevation data converter `convertMapboxElevationData`. However,
 * to use the Terrarium elevation data converter, use `convertTerrariumElevationData`.
 *
 * NOTE: This algorithm is limited to a GRID, meaning both the width and height must be equal and a power of 2.
 *
 * ## Examples
 *
 * ```ts
 * import { buildTerrainMesh } from 'gis-tools-ts';
 * // If using Terrarium elevation data:
 * // import { convertTerrariumElevationData } from 'gis-tools-ts';
 *
 * const elevationImage = await Bun.file(`${__dirname}/fixtures/fuji.png`).arrayBuffer();
 * const { terrain, vertices, triangles } = await buildTerrainMesh(elevationImage, 500, undefined, false);
 * ```
